I Application filed April 24, 1922 Serial No. 556,190.

To all whom it may concern:

Be it known that I, ALFRED O. GIRARD,

a citizen of the United States, residing at.

Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Dishwasher Nozzles, of which the following 1s a speclfication.

This invention is a novel form of dlSh washer, more specifically a nozzle for delivering water, soapy or clear, at the will of the operator onto dishes with sufficient force so that it is unnecessary to otherwise wash them.

The object of the invention is to provide a mechanism which can be applied to the hot water faucet of a kitchen sink, or elsewhere as the facilities of the user may dictate, and which, when so applied, can be conveniently used without any other mechanical ap ara-tus for readily washing dishes or ,ot e articles which have to be cleaned by the use of hot water and soap.

The invention consists of a device for attaining the foregoing objects, which can be easily and cheaply made, which is efficient and satisfactory in use, which is not readily liable to get out of order. More particularly, the invention consists in many features and details of construction which will be hereafter more fully set forth in the specification and claims.

Referring to the drawings in which like numerals designate the same parts through- 35. out the several views:

Figure 1 is a side view of mechanism illustrating this invention in its preferred form. Figure 2 is a sectional detail view through the device of Figure 1.

Figure 3 is a sectional detail view on the line 33 of Figure 2;

Figure 4 is an end view of the nozzle case taken, as indicated by the arrows 44, of Figure 2.

Figure 5 is a view in the opposite dlrection, as indicated by the arrows 5-5, and at the same point as Figure 4, showing the interior of the permanent fixture to which the nozzle is attached.

Figures 6,7 and 8 are sectional plan views through the three-way valve at the lines indicated by the corresponding arrows of Figure 2.

The device of this invention may be supplied from any suitable source with washmg l1qu1dpnesumab1y hot waterand water Wlll accordingly be referred to as the washmg agent without meaning thereby to l mit the scope of the use of the invention. The source of such hot water is symbolized 1nthe drawing by a flexible tube 10, enclosed at its end by handle 12 and secured at 14to the externally grooved lug 16 on a bracket member 18, to whose interlor water is delivered'throu 'h the passage 20 in member 16. Journale in bracket 18 is a threeway valve 22, manipulatable from outside the 'devlce by any conventional form of handle 24, and adapted to conventionally switch water delivered from pipe 10 through passage 20 to either one of two separated discharge ports 24 and 26 in the bracket, each opening inside of a cylindrical flange memher 28 provided with securing devices such,

for instance, as bayonet joints 30 for attaching the nozzle case 32 to this flange 28 and thereby to the bracket 18.

Nozzle case 32 is hollow and made with two interior water passages 34 and 36 leading to different selected groups of small discharge spray ports 38 and 40.

As shown in the drawing, the passage 36 is larger than passage 34 and its intake or righthand end, as viewed in Figure 2, is

made sufficiently large so that a suitable cup1n the particular case here illustrateda cylindrical one 42 may be inserted within the passage 36 in engagement with 2 suitable supporting lugs 44 in such a position that water delivered from passage 26 may enter the free open end 46 of the cup 42 and engage flakes or lumps of soap 48 I contained within the cup 42, principally atits opposite or closed end 50, and thence pass out of the case thnough a multiplicity of small side perforations 52, leading into the passage 36 proper, and thence to the discharge spray ports 40. A tube 53 is preferably inserted in port 26 and carried into case 42 beyond ports 52 so as to insure the waters making active contact with the soap 48.

In the operation of the device, when ass embled as shown in Figures 1 and 2, the operator first grasps the handle 12' and then moves the handle 24 of valve 22 to direct the hot water from pipe 10 into the soap 48 and thence to the spray ports 40. In so passing, the water takes u considerable soap and is delivered from tie ports 40 as soapy water which, on striking the dishes suitably disposed in a rack or the like, thoroughly cleanses them. As soon as the dishes are thus cleansed, the operator turns handle 24 to switch the water from passage 36 to passage 34, thereby directing clean hot water through spray ports 38 onto the dishes to thoroughly rinse them. The heat in the water should-be sufficient so that when the dishes are rinsed, they can be allowed to dry without wiping with a towel.

The operation of filling the device with soap is practically obvious: The operator merely rotates case 32 to releasethe bayonet joint connections 30, whereupon the soap receptacle 42 can be refilled, either with or without removing it from its position against the lugs 44. When the soap receptacle has been refilled, the nozzle 32 and attached parts are replaced inside of flange 28 and conventionally rotated to tighten bayonet joints 30.

Figures 4 and 5 show the end of passage 32 as of segmental cross-section34 and the end of passage 24, correspondingly as 24*. These are used merely to insure a free passage of water regardless of wear which may take place in the bayonet joints 30 to change lne angular position of the nozzle case 32 with reference to the bracket 18 when the parts are finally looked together.

What 1 claim is:

1. A dish washer nozzle of the class described having two groups of perforations for spraying the dishes and comprising two independent passages terminating in the groups of perforations, one of said passages being formed to hold a quantity of soap to be dissolved, a third passage for supplying water under pressure to the nozzle, the passages being so related in size as to insure the projection of sprays from the respective groups of perforations, and means for selectively directing water from said third passagethrough said independent passages to the groups of perforations.

2. A dish washer nozzle of the class described having two groups of perforations for spraying the dishes and comprising independent passages terminating in the groups of perforations, a perforate Wall in one of said passages for retaining a quantity of soap to be dissolved, a third passage for supplying water under pressure to the nozzle, the independent passages and said third passage being so related in size as to insure the projection of sprays from the re spective groups of perforations, and means for selectively directlng water from the third passage through said independent passages to the groups of perforations.

3. A dish washer nozzle of the class described having two groups of perforations forspra ing the dishes and comprising two indepen ent passages terminating in the groups of perforations, a removable perforate receptacle for soap in one of said pas-* sages, a third passage for supplying water under pressure to the nozzle, the passages being so related in size as to insure the projection of sprays from the respective groups of perforations, and means for selectively directing water from the third passage through said independent passages to the groups of perforations.

4. A dish washer nozzle of the class described having two groups of perforations for spraying the dishes and comprising two independent passages terminating in the groups of perforatlons, a third passage for supplying water under pressure to the nozzle, the passages being so related in size as to insure the projection of sprays from the respective groups of perforations, means for selectively directin water from the third passage through said independent passages to the groups of perforations, and a removable receptacle for soap in one of said independent passages so as to be engaged by water traversing the passage, said receptacle being cup-shaped and having an imperforate bottom wall and a erforate side wall, the open end of the cup geing disposed to receive water directed to said independent passage.

5. A dish washer nozzle of the class described and embodying a plurality of mem bers detachably secured to each other, one

of said members having two groups of per-' forations for spraying the dishes and comprising two independent passages terminating in the groups of perforations, one of said independent passages being enlarged to hold a quantity of soap to be dissolved, the other of said members comprising a third passage for supplying water under pressure to the nozzle, the third passage and the independent passages being so related in size asto insure the projection of sprays from the respective groups of perforations, and

means for selectively directing water from the third passage through said independent passages to the groups of perforations.

In witness whereof, I have hereunto subscribed my name.
